A supporting frame for a portion of a stem of a plant comprises a generally arc-shaped guiding member, two spacers projecting away from an inside concave surface of the guiding member, and a pressing member pivotally connected to the spacers. The guiding member, the pressing member and each spacer define a U-shaped cross-section for permitting insertion of the portion of the stem therein. The pressing member is deformable between an open position and a closed position. In the open position, the pressing member is away from the guiding member and the portion of the stem can be inserted between the guiding member and the pressing member. In the closed position, the pressing member is generally arc-shaped and substantially parallel to the guiding member, and the center of the pressing member is spaced away from the guiding member at a predetermined distance which corresponds substantially to the range of thickness of the stem in order to secure therein the portion of the stem after it has been inserted therein in the open position. Once the portion of the stem is secured in the frame, it has a predetermined curvature following the inside concave surface of the guiding member.
